new designs
Added First version of Orone-mini-S8A, DIY-able Maple-mini-like board.

First Commit of Orone-mini and Orone-mini-S8A-v0r001, Maple-mini-like STM32F board.
Updated README to show addition of Orone-mini
Added USB-Mini-Molex.lbr which contains three different footprints for the Molex socket. Updated README files to reflect untested status.
Segregated ground plane under ADC signals re-connected to av-. Intent is to provide a less noisy ground plane under ADC input signals.
Created initial Bill of Materials (BoM) using RS, Farnell & Future (for ESD only). TBD: 100uF capacitor. Modified CAD to hide redundant airwires.
Added Orone-mini-S8C, modified BoMs for S8A and S8C variants, added markdown to README
Corrected small error in markdown.
Tweaked position of User LED (pin 33) and added thru-hole pad for DISC (PB9) putting holes onto 0.1" grid. These give access to the two signals not on pin-headers, though the User LED must not be fitted.
Updated README's describing 'Tweaked' position of User LED pads and DISC 'via' to give access to signals.
First checkin of Orone-mini-S8D, puts User LED (33) next to pin header, and DISC signal onto a pad. Also changed position of Power-on and User LED.
Moved BoM files into their own directory, and added costs from RS and Future.
Updated top-level README.md to explain the Orone-mini-S8D.
